Diamond dies - Natural diamond wire dies (ND dies)

Features

Esteves Group is a manufacturer of diamond drawing dies with natural diamond (ND) blanks inside as a high quality, predictable and durable product for drawing ferrous and non-ferrous wires 0.007 to 2.00 mm (.00019-.0787"). Larger sizes are available by request.

Like all products from Esteves Group you can expect these products to be manufactured with the highest quality and accuracy standards.

Natural diamonds, abbreviated as ND, are naturally formed within the earth at high pressure high-temperature conditions. Because of its extremely rigid lattice, it can be contaminated by a few types of impurities such as boron and nitrogen.

The ND blanks that Esteves Group use are all selected for purity and limited inclusions, flattened on a special lapping machine, and sorted in different groups of height and diameter combinations.

Key benefits of Esteves Group ND diamond wire dies

•Long die life due to its extreme hardness and resistance to scratching•Can be used in high-heat processes because of its extreme thermal conductivity•Blanks are thermally stable up to 1700°C (3092°F)•Easy setup, smooth drawing•100% of all diamonds are checked for inclusions, cracks•Nonconductive properties make this product a good choice when electrical conductive materials are an issue

Applicability

Natural diamond has been used as a raw material for drawing dies for over 100 years. These natural diamond dies were the first types of drawing dies that were manufactured by Esteves Group.

SSCD and PCD blanks were invented in recent decades and are gradually replacing natural diamond dies in some applications.

Natural diamond dies are still successfully used for applications that require excellent wire surface qualities, high heat resistance and in applications that require a die material that is not electrically conductive.
